THE cancellation of Japanese superstar Namie Amuro's concert in Singapore has left the concert promoter here bewildered.When contacted by My Paper, local concert promoter Midas Promotions said they were left "somewhat perplexed" after they were told by the promoters in Japan that the show had been cancelled, just one week before Amuro was set to perform on Friday at the Singapore Indoor Stadium."We had paid the artiste fee in full, booked the venue and obtained all the necessary licences. Production was ready for her arrival," said Mr Steven Woodward, general manager of Midas Promotions' Singapore office.He said the Japanese promoter had cited a breach of agreement as the reason for the cancellation, but he contends that his company has "fulfilled the agreement in full and to the letter".Notice of refunds will be announced soon, he said.J-pop fan electronic engineer Leon Wei, 30, said that he will continue to support Japanese gigs coming here.However, account executive Amelia Ng, 27, said that this was the "last straw" with Midas Promotions. "When the concert was cancelled, I gave them a call but I did not get a satisfactory answer. I don't think I would risk buying from them again," she said.
